Coma

Coma is the severest impairment of arousal and is defined as the inability to obey commands, speak, or open the eyes to pain.

Scoring

The Glasgow Coma Scale (GCS) is a widely used scoring system with good repeatability (note: the scale is used to assess level of consciousness and is not designed for following neurologic deficits). General practice is to record a “T” (for “intubated”) next to the verbal score and the total score for patients whose verbal axis cannot be assessed because of intubation.

No single GCS score defines a cutoff for coma, however, 90% of patients with GCS ≤ 8 and none with GCS ≥ 9 meet the above definition of coma. Thus, GCS ≤ 8 is a generally accepted operational definition of coma.

A number of scales for use in children have been proposed.
